Definitions

  • the invention relates to a linear guide, in particular for Clamping tools, with a guided in or on a slide bed, movable carriage which carries at least one first clamping jaw, the relative to a fixed, connected to the sled bed, second jaw is movable and in the sled bed or in Slide at least two in the direction of movement of the slide extending grooves provided in a plane opposite one another are.
  • Such a linear guide or such a clamping tool is known for example from US Pat. No. 2,518,102.
  • a movable sled carried by a sled bed, being in Sled bed and sled grooves are provided in one Variety of bearing balls are used to reduce the friction between Reduce sled and sleigh bed.
  • linear guides have a not insignificant Play between sled bed and sled so that theirs Use in clamping tools in which workpieces are clamped that are about a machining in corresponding Processing machines to be subjected is problematic.
  • the demand for a play-free guidance of the slide or the the movable jaw connected to it is therefore also special important because the tension created and the resulting Counterforce on the workpiece does not act on a common level, so that there is a torque that the slide with play Can raise the guide or push it down and tilt it.
  • the invention has for its object a sled bed and Slides to create existing linear guides, their manufacture is simplified, and with the help of workpieces or the like nevertheless clamped practically free of play with great accuracy can be.
  • This object is achieved according to the invention in a linear guide of the generic type in that the first The clamping jaw is sliding against the sled bed so that the area of the slide facing away from the first movable clamping jaw reaches under the second clamping jaw connected to the sled bed and sliding against them, that in the sled or in the sled bed at least two pairs of spaced apart opposing thrust pieces are arranged, which in the engage respective, opposite grooves and that the Pressure piece pairs with respect to their height relative to the grooves in different levels are arranged.
  • the movable first jaw of the Sled free of play against the sled bed or the sled against the second, fixed clamping jaw pressed so that exactly defined backlash-free Abutments are available through which the three-dimensional position of the clamped workpiece is precisely defined.
  • the Sled and the sled bed as well as the grooves with comparatively low manufacturing accuracy can be produced, the still permissible tolerance range in contrast to the prior art a power of ten can be larger.
  • the in the sled bed in the longitudinal direction of the direction of movement Slotted grooves are preferably V-shaped grooves trained, the groove flanks are inclined to each other. Thereby take the appropriate choice of the height of the pressure piece pairs Pressure pieces on opposite flanks and produce on them The pair of forces mentioned at the beginning.
  • the pressure pieces are designed as balls or cones, which, for example, in a bore of the carriage inserted and by a coil spring arranged in the bore are biased and pressed against the groove flanks.
  • the pressure pieces as spring washers or spring washers or spring washers or Form spring washer segments and in slots or bores of the slide.
  • spring washers or spring washer sections can on the insertion of a additional compression spring can be dispensed with.
  • this has Sled bed on an approximately U-shaped cross-section in which the longitudinally movable carriage is arranged.
  • the Grooves can be in the direction of movement of the slide on the inside the longitudinal leg of the U-profile run, it is but of course also possible, the grooves in the carriage and to provide the pressure pieces in the sled bed, if the different altitude of the above mentioned with each other acting parts is observed.
  • the clamping tool shown in Fig. 1 consists essentially from a U-shaped carriage bed 1, in which a carriage 2 is guided. On the carriage 2 serves a threaded spindle 3, which in the carriage 2 by means of a Bearing 4 is mounted and with its end 5 in a cavity 6 of the sled bed 1 engages. Above the sled bed 1 is a movable one on the right side of the illustration Clamping jaw 7 arranged, which is fixed with the also movable Carriage 2 is connected. The jaw 7 is one fixed jaw 8 opposite, which in turn firmly with the Sled bed 1 is connected. Between the jaws 7 and 8, a schematically represented workpiece 9 can be clamped become.
  • the carriage 2 is in the carriage bed 1 with the help of opposite Grooves 19 and 20 performed on the inside the longitudinal leg of the U-shaped carriage bed 1 in the direction of movement of the carriage 2 are formed and in one common horizontal plane.
  • the grooves have a V-shaped profile, the groove flanks 21 and 22 are inclined to each other.
  • Pressure pieces 23, 24 and 25, 26 engage in the grooves 19 and 20, respectively a, which is held in bores 27, 28 and 29, 30 of the carriage 2 become.
  • the pressure pieces 23 and 24 and 25 and 26 form each pair of pressure pieces 31, 32, the respective Pressure piece pairs 31, 32 on common, with respect to their altitude however, there are different horizontal planes.
  • the pressure pieces 23 to 26 are designed as balls that with With the help of spiral springs in the respective grooves.
